The Indian Navy’s annual theatre-readiness operational exercise (TROPEX) is now underway, being carried out off India's Western Seaboard.

The TROPEX 17 programme began last week and will continue for another month. It will see several vessels and aircraft from the Indian Navy’s Western and Eastern Naval Commands exercising together, which are also due to be joined by assets from India's army, air force and coastguard.

The current exercise will witness the participation of the Indian Navy's major surface combatants and air-assets, having increased both in scale and complexity over the last few years.

TROPEX participants include the Landing Platform Dock (LPD) Jalashwa, aircraft-carrier Vikramaditya, the recently commissioned destroyer Chennai, nuclear submarine Chakra and the P-8I long-range maritime-reconnaissance vessel in addition to anti-submarine warfare aircraft.

"TROPEX is designed to be conducted in several phases, both in harbour and at-sea, covering different facets of warfighting and combat operations."

A range of SU-30 MKI, Jaguars and AWACS, as well as the Indian Air force's IL-78 Flight Refuelling Aircraft and the Indian Army's Infantry units will also be participating in the exercise.

TROPEX is designed to be conducted in several phases, in harbour as well as at sea, and will cover different facets of warfighting and combat operations.

The TROPEX 17 programme has become a significant aspect of current security requirements, focusing on testing the combat readiness of the combined fleets of the Indian Navy, in addition to the assets of the Indian Air Force, Indian Army and the Indian Coast Guard. The exercise will also help boost inter-operability and successful joint operations in complex scenarios.

The previous edition of the TROPEX was conducted by the Indian Navy in January 2015.
